Continuing north from Tuwanek Beach Marine Park about 1 mile (1.6 km) you come to Oyster Beach Marine Park that has 3 or 4 tent sites, a fire pit, an outhouse but no water. It has the same problem of poor anchorage for your boat on windy days but great for day trips.
Another .6 miles (1 km) – 7 miles from Porpoise Bay wharf – takes you past an oyster farm where you will see blue barrels anchored in rows. At the northerly point of the farm you will find a pair of pictographs on a rock bluff. These two paintings are fairly basic and I have heard two theories as to their purpose. The first is that the paintings depict Tchain’-ko, the Sea-Serpent, god of the waters. The story goes that this marks where a shíshálh (Sechelt) hunter was drowned by a porpoise that he had harpooned and when the people later passed by the area they noticed a fresh scar on the mountainside above the site, something only Tchain’-ko could do.
The second thought is that these pictographs let others know that there was good fishing here. Not quite as dramatic.
